Unit testing
TestNG
JUnit lifecycle @BeforeClass For each @Test Instanciate test class @Before Invoke the test @After @AfterClass
JUnit advanced @Rule and @ClassRule Parametrized Mocks Hamcrest
JUnit @Rulepublic class MyRule implements TestRule { @Overridepublic Statement apply( Statement base, Description description ) {return new MyStatement( base );}}
JUnit @Rulepublic class MyStatement extends Statement { private final Statement base;public MyStatement( Statement base ) {this.base = base;}
@Overridepublic void evaluate() throws Throwable {System.out.println( "before" );try { base.evaluate();} finally { System.out.println( "after" );}}}public class MyRule implements TestRule { @Overridepublic Statement apply( Statement base, Description description ) {return new MyStatement( base );}}

Mockito
Mockito is a mocking framework for unit tests in Java
Mockitoimport static org.mockito.Mockito.*;import static org.junit.Assert.*;import java.util.Iterator;import org.junit.Test;[email protected] void iteratorWillReturnHelloWorld(){//arrangeIterator i=mock(Iterator.class);when(i.next()).thenReturn("Hello").thenReturn("World");//actString result=i.next()+" "+i.next();//assertassertEquals("Hello World", result);}
HamcrestHamcrest is a matchers framework that assists writing software tests
HamcrestassertTrue(foo.contains("someValue") && foo.contains("anotherValue"));
HamcrestassertTrue(foo.contains("someValue") && foo.contains("anotherValue")); assertThat(foo, hasItems("someValue", "anotherValue"));
vs
HamcrestassertTrue(foo.contains("someValue") && foo.contains("anotherValue")); assertThat(foo, hasItems("someValue", "anotherValue"));
vsassertThat( table, column("Type",contains("A","B","C")).where(cell("Status", is("Ok"))));Another example:
